Eases Email Automation, Simple to Use

I use Twilio SendGrid Email API for their automated emails, particularly enjoying its capability to connect to our point of sale system so we don't have to manually upload anything. It's very easy to use and user-friendly. I also like their ability to manage unsubscribes, which is very easy. The initial setup of Twilio SendGrid Email API was extremely easy.
